Koru Coiled Spiral Metal Sign

About the Coiled Spiral design

A single white channel coils through this black disc, starting as a hairline sliver near the left rim. It swells as it sweeps over the top and around the right side, reaching its widest along the bottom. From there it tightens into a smaller turn and finishes in a pointed hook just below the center, curled around a round knob of steel. The rim stays unbroken all the way around, like the edge of a coin.
